Do not put allocated block into HeapObjectsMap · 55674264

yurys@chromium.org authored Nov 29, 2013

Heap allocation reported to AllocationTracker may be later divided into several objects so it is incorrect to put the block as a new HeapObject into the map. We will match allocated block with actual HeapObjects later when iterating Heap (will be addressed in another patch). Since the objects are not assigned an id immediately after creation we need to call FindOrAddEntry when finding id for SharedFunctionInfo during stack crawling.

Removed hooks for tracking creation of AllocationMemento. AllocationMemento is not a HeapObject and should be considered as implementation overhead.

Renamed NewObjectEvent to AllocationEvent which is more precise in case of folded allocations and when a part of the new block becomes AllocationMemento.

Currently it's in the Code object for some ICs and in ICs for other ICs.
This should make it easier to alter bits as needed.

2) Recover an extra bit in the code object to give us 6 bits for the extra ic state. We'll need it soon to store contextual state.

3) Cleanup code that treated StrictMode enum and ExtraICState enum as interchangeble.
